GOVERNMENT RIGHTS

The United States Government has certain rights in this invention pursuant to Contract No. DE-AC07-05ID14517 between the United States Department of Energy and Battelle Energy Alliance, LLC.

TECHNICAL FIELD

The present invention relates to a material forming tool, and method for forming a material, and more specifically to a friction stir welding tool which has parts which are replaceable, and which is further useful in forming materials which may comprise alloys, composites or the like.

BACKGROUND OF THE INVENTION

The prior art is replete with numerous examples of friction stir welding devices which are useful in welding various materials. As a general matter, friction stir welding is a technique whereby a rotating tool is brought into forceable contact with an adjacent work piece to be welded, and the rotation of the tool creates frictional heating of the adjacent work piece, and extensive deformation as mixing occurs along a plastic zone. Upon cooling of the plastic zone the work pieces are joined along a welding joint. Examples of prior art friction stir welding devices and other methodologies are more fully disclosed in U.S. Pat. Nos. 4,636,124; 5,460,317; 5,769,306; 5,971,247; 6,079,609; 6,173,880; 6,230,957; 6,237,835; 6,259,052; 6,484,924; 6,613,447; 6,619,534; and 6,729,526, the teachings of which are incorporated by reference herein. It is generally agreed that friction stir welding allows for the autogenous welding of joints with no alloying effects caused by traditional melting operations, such as may be achieved by plasma welding, laser welding, tungsten inert gas welding, etc. As a general matter, friction stir welding typically preserves more of the cast micro-structural properties than other welding methods.

Researchers and designers have faced many challenges with respect to the creation of various new alloys and composite materials which may be used in various industrial and military applications. For example, many new materials are needed where the material needs to possess several different conflicting material properties. For example, extensive research has focused, as of late, on the production of lightweight composite armor, that is, armor which provides protection from large caliber rounds, but which is lightweight so that it may be placed or deployed on mobile platforms. In lightweight armor, conflicting material properties present themselves, for example, the new armor must have a desirable microstructure for ballistic resistance and fatigue performance while simultaneously possessing characteristics of ease of forming and joining. The same armor must possess sound ballistic resistance on the outside facing surface of same, and good structural properties on the inwardly facing surface and which are favorable for structural and ballistic designs.

Therefore, a material forming tool and a method for forming a material which addresses these and other shortcomings in the prior art practices and techniques utilized heretofore is the subject matter of the present application.

SUMMARY OF THE INVENTION

A first aspect of the present invention relates to a method for forming a material which includes providing a first material; providing a second material, and placing the second material into contact with the first material; and locally plastically deforming the first material so as mix the first material and second material together to form a resulting material having characteristics different from the respective first and second materials.

Another aspect of the present invention relates to a method for forming a material which includes providing a first metal; providing a second metal, and positioning the second metal in juxtaposed relation relative to the first metal; providing a tool and imparting axial force, and rotational movement to the tool; and contacting the tool with the first and second metals and imparting sufficient axial force and rotational movement to the tool so as to locally plastically deform and mix the first and second metals and form a resulting material having physical characteristics different from the respective first and second metals.

Still another aspect of the present invention relates to a material forming tool which includes a shank portion; a shoulder portion which releasably engages the shank portion; a pin which releasably engages the shoulder portion, and wherein the pin defines a passageway; and a source of a material coupled in material flowing relation relative to the pin.

These and other aspects of the present invention will be described in greater detail hereinafter.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

This disclosure of the invention is submitted in furtherance of the constitutional purposes of the U.S. Patent Laws “to promote the progress of science and useful arts” (Article 1, Section 8).

A material forming tool of the present invention is generally indicated by the numeral 10 in FIG. 1 and following: Referring now to FIGS. 1 and 2, for example, the material forming tool 10 of the present invention is illustrated and which includes a shank portion 11. The shank portion is defined by an elongated main body 12, which has a first end 13, and an opposite second end 14 which is forcibly engaged by a machine (not shown) and which imparts rotational movement to the shank as indicated by the arrows as placed in the various drawings. The main body is defined by an exterior facing surface 15, and an opposite interior facing surface 20 (FIG. 2). As seen in FIGS. 1 and 2, the shank portion, and more specifically the exterior-facing surface 15 may be defined by a first outside diametral portion 21, and a second portion 22 has a second outside diametral dimension. As illustrated, the first outside diametral portion is greater in cross sectional dimension than the second portion. As illustrated in FIG. 2, the first portion, having the first outside diametral dimension 21, is positioned adjacent to the first end 13 of the main body, and the second portion 22 is positioned adjacent to the second end 14 thereof. It should be understood in other forms of the invention (not shown), the shank portion of the material forming tool may be substantially uniform in its outside diametral dimension when measured between the first and second ends 13 and 14, respectively. As will be appreciated to one skilled in the art, the first portion 21, and the second portion 22 may have various outside diametral dimensions depending upon the use of the material forming tool 10, that is, the amount of pressure that the tool might experience in operation, and the thermal coefficient of expansion of the various materials that might be utilized to fabricate the individual portions of the material forming tool 10 as will be described in greater detail hereinafter.

Referring still to FIG. 2, the interior facing surface 20 of the main body 12 as noted above, defines a longitudinally extending passageway 23 which extends from a first end 24 to a second end 25. The longitudinally extending passageway 23 has a first portion 30 which has a diminishing diametral dimension, when this dimension is measured from the first end 24 of the passageway 23 in the direction of the second end 25 thereof. As seen in FIG. 2, for example, this first portion 30 of the passageway is generally characterized by a taper such as a Jacob's Taper #1, or a pin taper #8. In the form of the invention as seen in FIGS. 1 and 2, it will be understood that the first portion 30 of the passageway 23 has a first end 31, which is adjacent to the first end 13 of the main body 12, and an opposite second end 32, which is defined by a circumscribing seat 33. Still further, the longitudinally extending passageway 23 has a second portion 34 which has a first end 35 and an opposite second end 36 which is positioned adjacent to the second end 14 of the main body 12.

As best understood by a study of FIG. 2, the material forming tool 10 of the present invention includes a shoulder portion which is generally indicated by the numeral 50, and which is releasably engageable with the shank portion 11. As best illustrated, by a study of FIG. 2 and following, the shoulder portion has a main body 51, with opposite first and second ends 52 and 53, respectively. Still further, the main body has an exterior facing surface 54 which has a plurality of circumscribing channels 55 formed therein. The circumscribing channels act to control heat flow within the material forming tool 10 during the material forming process. It should be understood that the shoulder portion may be cooled by a supplemental means in order to dissipate heat energy which is generated during the material forming process as will be described hereinafter. As seen in FIG. 2 and following, the shoulder portion 50 includes a male member which is generally indicated by the numeral 60, and which is releasably matingly received within the first portion 30 of the longitudinally extending passageway 23 which is defined by the shank portion 11. The male member has a main body 61 with a first end 62 and an opposite second end 63. Still further, the male member is defined by an exterior facing surface 64, and an interior facing surface 65. As understood by FIG. 2 and following, the male member is operable for substantially telescoping and frictional engaging receipt within the longitudinally extending passageway 23, and more specifically the first portion 30 thereof. This arrangement allows for the shoulder portion to be easily detached and replaced based upon the operational needs, and wear and tear as experienced by the shoulder portion 50.

As seen in FIGS. 2, 3 and 4, the shoulder portion 50 defines, by means of the interior facing surface 65, a pin passageway which is generally indicated by the numeral 70. The pin passageway has a first end 71, and an opposite second end 72. Still further, as seen in FIG. 2, for example, the pin passageway is characterized by a first portion 73, and a second portion 74 which communicates with same. As seen in FIG. 2, the pin passageway has a diminishing inside diametral dimension when this is measured in a direction which extends from the first end 71 in the direction of the second end 72 thereof. Still referring to FIG. 2, 3 and 4, the material forming tool 10 of the present invention includes a pin 80, which is releasably engageable with the shoulder portion 50, and which is operable to engage a work piece as will be discussed in greater detail hereinafter. The pin 80 includes a main body 81 which has a first end 82 which engages the work piece as will be described, and a second end 83 which is received in the pin passageway 70 as defined by the shoulder portion 50. As illustrated, the pin 80 is telescopingly received, at least in part, in the pin passageway 70, and extends generally longitudinally outwardly relative to the first end 52 of the main body 51. As illustrated, the pin has an intermediate portion 84, and the outside diametral dimension of the main body 81, of the pin 80, diminishes when measured from a position beginning at the intermediate portion 84, and extending longitudinally, outwardly to the opposite first and second ends 82 and 83 thereof. In an alternative embodiment (not shown), the pin may have a substantially constant radius. As illustrated in the drawings, the pin is releasably frictionally engaged by the main body 51 of the shoulder portion 50. The outside diametral dimension of the pin forms a taper which allows a portion of the pin to be telescopingly and frictionally received within the pin passageway 70. In the arrangement as seen in FIGS. 2, 3 and 4, a passageway 85 is formed through the main body 81 of the pin. The passageway has a first end 86 and an opposite second end 87. The passageway 85 is coupled in fluid flowing relation relative to the pin passageway 70 which, in turn, is coupled in fluid flowing relation relative to the longitudinally extending passageway 23. As illustrated in FIG. 2, the distal second end 87 of the passageway 85 may be positioned in spaced relation relative to the first end 82, or as illustrated in FIG. 3, the passageway 85 may extend substantially longitudinally therethrough extending from the first end 82 to the second end 83 thereof. In yet another form of the invention, it should be understood that the passageway may terminate at several locations. The purpose of the passageway 85 will be discussed in greater detail, hereinafter. In the arrangement as shown, the shank portion 11, shoulder portion 50 and pin 80 can be fabricated from the same and/or dissimilar materials and may further have a similar thermal coefficient of expansion. Depending upon the work piece that will be engaged, and which will be discussed hereinafter, the shoulder portion 50, and pin 80 may be fabricated from a metal or metal alloy which is selected from the group comprising high temperature refractory metals such as tungsten, molybdenum, and their alloys, and further including ceramics such as boron nitride and related compounds, as well as tungsten and their related carbides.

Referring now to FIG. 4, it will be seen that the material forming tool 10 of the present invention may be coupled in fluid flowing relation relative to a source of particularized material such as a source of particularized metal 90 by means of a conduit which is generally indicated by the numeral 91. The conduit 91 is coupled in fluid flowing relation relative to the first end 14 of the shank 11, and more specifically to the longitudinally extending passageway 23. Acting upon the source of particularized material is a pump 92 of conventional design. The pump constitutes a means for pumping the source of particularized material from the source 90 into the passageway 23 so as to deliver same at the second end 87 of the passageway 85 which is defined by the pin 80. This technique of delivering the particularized material is defined as “rotational loading” of the material hereinafter. This arrangement will be discussed in greater detail hereinafter, particularized metal can pass through the material forming tool 10 and exit through the pin 80 for the purposes which will be described in the methodology which is set forth in greater detail below. Still further, and referring still to FIG. 4, it will be understood that the present invention includes a means for imparting axial force, as indicated generally by the arrow labeled 93, and a means for imparting rotational movement 94 as indicated by the arrow labeled 94. Such forces are typically provided for by means of a conventional milling machine which can provide both the axial and rotational force to render the material forming tool 10 operational. Referring now to FIG. 3, it will be seen that in another form of the invention, a source of a solid/continuous wire 95 formed of a given material can be provided, and which is supplied to the passageway 23 defined by the shank 11. As seen, by the drawings, a means for driving a continuous wire 96, is provided and the distal end 97 of the continuous wire 95 exits the first end 82 of the pin 80, through the passageway 85, and more specifically the second end thereof 87. This is another means of rotationally loading the continuous wire 95.

Referring now to FIGS. 5-10, respectively, it will be seen that the method of forming a material of the present invention is generally indicated by the numeral 100 and includes the steps as will be discussed below. In the methodology of the present invention 100, a material forming tool 10 is provided and which is operable to engage a work piece which is generally indicated by the numeral 101. As seen by reference to FIGS. 9A, 9B, 9C, FIG. 7, and FIG. 11, the work piece may include a number of different material layers which may be oriented in either a horizontal (FIG. 9A-C) or vertical (FIG. 11) orientation. For example, the methodology may include a first step of providing a first material which is generally indicated by the numeral 102; providing a second material 103; and providing a third material 104, respectively, and which are disposed in juxtaposed relation one relative to the other. Still further, and referring now to FIG. 9C for example, it will be seen that the methodology 100 could include the steps of providing a work piece 101 which has different portions 102, and which are disposed in predetermined spaced relation one relative to the other, and providing a second material 103 which is positioned therebetween for the purposes as will be described hereinafter. Referring now to FIG. 5, for example, a method for forming material 100 of the present invention is generally shown, and which includes the steps of providing a first material 102; providing a second material 103, here illustrated as the source of particularized material 90 which may include metal, ceramic and other similar materials, and placing the second material 103 into contact with the first material. As illustrated, the method further includes the step of imparting axial force 93, and rotational movement 94 to the tool 10 thereby locally plastically deforming 105 the first material so as mix the first-material and second material together to form a resulting material 106 having characteristics different from the respective first and second materials. In the illustration as seen in FIG. 5, the step of locally plastically deforming 105 the first material 102 further includes the steps of frictionally heating and rotationally loading the first material. As seen in FIG. 5, the particularized material 103 exits through the passageway 85, at the distal end 87, and into the plasticized region 105 where it is mixed with first material as illustrated. As should be understood, in the present methodology, the first and second materials 102 and 103, respectively, may be non-metals. Still further, the first material 102 may comprise a metal, and the resulting material 106 may result in an alloy. Still further, the resulting material 106 may result in a composite. Additionally, it should be understood that the first material 102 may include a metal and the second material may include a non-metal. Additionally, and in the arrangement as shown, the methodology may be useful in combining two different metals. Additionally, the methodology may be useful in combining a first material which includes a non-metal, and a second material which comprises a metal. As illustrated most clearly by reference to FIG. 6, in the methodology 100 as described, the first and second materials 102 and 103 are each substantially continuous, and the plasticized region 105 is effective for mixing the first and second materials 102 and 103 together to provide a resulting material 106. Again, as seen in FIG. 5, in the methodology as described, at least one of the first or second materials 102 and 103 may be particularized and may be rotationally loaded.

Referring now to FIG. 7, it will be seen that the methodology 100 includes a step of providing a third material 104 which is placed into contact with the first and second materials 102 and 103. The methodology 100 further includes the step of locally plastically deforming the first, second and third materials so as form a resulting material 106. In one of the several forms of the invention as seen, the step of locally plastically deforming the first material 102 comprises the steps of providing a tool 10, and simultaneously imparting axial force 93, and rotational movement 94 to the tool; contacting the tool with the first material 102 so as to locally plastically deform 105 the first material; and supplying a particularized second material 103 to the first material which has been previously locally plastically deformed by the axial force and rotational movement of the tool 10.

Referring now to FIG. 8, in the methodology 100 as described above, the second material 103 may further comprise a source of a continuous wire 95, and the methodology includes a step of supplying the substantially continuous wire to the first material 102 which has been previously locally plastically deformed 105 by the simultaneous application of the axial force 93, and rotational movement 94 of the material forming tool 10. As seen best by FIG. 5, the step of supplying the particularized second material 103 to the first material 102 may further include the steps of providing a passageway 85 in the tool 10; and delivering the particularized second material 103 to the locally plastically deformed first material 102 by way of the passageway 85. Further, and referring to FIG. 8, the step of supplying the substantially continuous wire 95 to the first material 102 further includes the steps of providing a passageway 85 in the tool; and delivering the substantially continuous wire of the second material 103 to the locally plastically deformed first material 102 by way of the passageway 85.

Referring now to FIGS. 5-8, the method for forming a material 100 of the present invention includes the steps of providing a first material 102 which may comprise a metal; providing a second material which may comprise a metal 103, and positioning the second metal in juxtaposed relation relative to the first metal; providing a tool 10 and imparting axial force 93, and rotational movement 94 to the tool; and contacting the tool with the first and second metals 102 and 103 and imparting sufficient axial force and rotational movement to the tool 10 so as to locally plastically deform 105 and mix the first and second metals, and form a resulting material 106 having physical characteristics different from the respective first and second metals 102 and 103, respectively. As seen in FIG. 6, the first and second metals 102 and 103 are substantially continuous surfaces which are juxtaposed, one relative to the other. Referring now to FIGS. 9A and 9B, respectively, it will be seen that the first and second metals 102 and 103 have a combined thickness dimension, and wherein the resulting material 106 which is formed from same has a thickness dimension which is substantially equal to the combined thickness dimension of the first and second metals. Still further and based upon the materials used, the resulting material 106 may have a thickness dimension which is less than combined thickness dimension of the first and second metals. Referring now to FIG. 9A, it will be seen that the first and second metals or first and second materials 102 and 103 may each have substantially the same thickness dimension. Further, referring now to FIG. 9B, it will be seen that the first and second materials or metals 102 and 103 may each have a different thickness dimension. Still further, referring now to FIG. 9C, in the methodology as described, the step of providing the first and second materials or metals 102 and 103 may further include the steps of providing at least two layers of one of the first or second metals, and locating the two layers in spaced relation one relative to the other; and positioning the remaining metal layer therebetween the two layers of the first and/or second material or metal 102 and 103, respectively. In the arrangement as seen in FIG. 9C, for example, the at least two layers of the first or second material or metal 102 or 103 may each have substantially the same thickness, or in the alternative have different thickness dimensions.

Referring now to FIG. 10, the work piece 101, includes a first continuous layer 110 having given dimensions, and further, a second continuous layer 111 is appropriately sized, and then placed in covering relation over a plurality of cavities 112 which are formed in a predetermined pattern in the first continuous layer 110. As should be understood, the second continuous layer 111 may be formed from the same material as the first continuous layer, or may further be formed from a different material. As illustrated in the exploded view of FIG. 10, a second material such as the particularized material 90 is delivered into the respective cavities 112. Thereafter, the second continuous layer 111 is placed in covering relation relative thereto and the work piece 101 as seen in FIG. 10 is acted upon by the material forming tool 10 in the manner as seen in the earlier drawings. Therefore, in the methodology 100 as described, one of the first or second materials 102 or 103 is a substantially continuous layer of metal which defines, at least in part, a cavity 112 and wherein the remaining metal 103 is particularized and deposited within the cavity.

Referring now to FIG. 11, an alternative arrangement of a plurality of materials including the first, second and third materials 102, 103 and 104 are shown in a vertical arrangement, and which can be engaged by the material forming tool 10 of the present invention.

In the methodology as described, the step of contacting the tool 10 with the first and second materials 102 and 103, which may comprise various metals, further comprises maintaining the rotating tool in contact with the first and second materials 102 and 103 for a time period which is effective to produce a resulting material 106 which is substantially uniform. Further, and referring now to FIG. 5, the step of contacting the tool 10 with the first and second materials or metals 102 or 103 further comprises maintaining the rotating tool in contact with the first and second materials or metals 102 and 103 for a time period which is effective to produce a resulting material 106 which is not uniform throughout. In the arrangement as seen, the first and second materials or metals 102 and 103 are selected from the group which comprise metals, metal alloys, metal ceramics and metal composites.

Operation

The operation of the described embodiment of the present invention is believed to be readily apparent and is briefly summarized at this point.

Referring now to FIGS. 3 and 4, a material forming tool 10 of the present invention is shown, and which includes a shank portion 11; a shoulder portion 50 which releasably engages the shank portion; a pin 80 which releasably engages the shoulder portion, and wherein the pin defines a passageway 85; and a source of a material 90 or 95 coupled in material flowing relation relative to the pin. In the arrangement as shown, the material forming tool 10, and more specifically the pin 80 thereof, has a first, proximal end 82, and an opposite, distal, second end 83, and wherein the passageway 85 extends from the first end 82 in the direction of the second end. As seen in FIGS. 3 and 4, the source of the material 90 is received in the passageway 85 at the one end, and is discharged from the pin at a location which is adjacent to the opposite end. As illustrated in FIGS. 1 and 2, the shoulder portion 50 is coupled in material flowing relation relative to the pin 80, and the source of the material 90, for example, is supplied to, and flows through, the shoulder portion, and into the passageway 85 which is defined by the pin. As illustrated in FIGS. 1 and 2, the passageway 85 terminates at a single location 87 which is adjacent to one end of the pin 80. However, it should be recognized that the passageway 85 may terminate at a plurality of locations which are adjacent to the end of the pin. This arrangement would be helpful in manufacturing an alloy, or composite, for example, which has a gradation in its overall structure. As seen in the various drawings, the passageway 85 is operable to receive a source of particularized material, or further a solid and continuous wire as shown in the drawings (FIG. 3).

The method for forming a material 100, of the present invention, includes the steps of providing a first material 102; providing a second material 103, and placing the second material into contact with the first material; and locally plastically deforming the first material 105 so as mix the first material and second material together so as to form a resulting material 106 having characteristics different from the respective first and second materials. As was discussed, the method for forming a material 100 of the present invention also includes the steps of providing a first material or metal 102; providing a second material or metal 103, and positioning the second metal or material in juxtaposed relation relative to the first metal or material; providing a tool 10 and imparting axial force 93, and rotational movement 94 to the tool; and contacting the tool with the first and second metals or materials and imparting sufficient axial force and rotational movement to the tool so as to locally plastically deform 105 and mix the first and second metals and/or materials together to form a resulting material 106 having physical characteristics different from the respective first and second metals or materials 102 and 103, respectively.

Therefore it will be seen that the material forming tool 10 and method for forming a material 100 of the present invention provides many advantages over other tools and techniques which have been developed heretofore and which have been useful in the formation of various materials. As presently disclosed the present material forming tool can be quickly disassembled, repaired and replaced in a fashion not possible heretofore with respect to other similar tools.
